Brass nozzle head

Do anyone know if the brass nozzle heads contain lead? and actually put lead into the prints ?

 

Who has the best steel nozzles?

 

The hex hotend can use nozzles for the E3D V6 as well. I would check @Printed Solid for stock. Not sure if you were looking at staying with the stock .4mm nozzle size or not.

 

Interesting..Didn't think of that. I'm going to swap out the brass nozzle on the R2. any more thoughts sticking with 4mm? why would i changed that? is there specific prints that need an alternate nozzle size?

 

There are several reasons to switch nozzle sizes. Printing with woodfill filament and such you may want to go to a .5mm or .6mm nozzle. A larger nozzle will also give you quicker print times. You want fine detail, then going to a .25 or even crazier the .15 nozzle size will give you crazy detail. The smaller you go the slower you need to print though. Also you have to make sure to adjust your layer heights since you don't want to go above 75% the nozzle size. Sticking with .4mm should do you well for most of what you print.

 

One thing to consider with the R2 is that they are using an IR height sensor that requires the distance from the tip of the nozzle and the sensor to be a set value. The E3D nozzles will add to that distance. Not sure how much adjustment is on the sensor board to maintain the distance. You don't want the nozzle to hit the build plate prior to the sensor activating. Just food for thought.

 

That's a great point you bring up, Thanks!

 

Correct, I'm planning...
